DUNLITE UVR100 AUTOMATIC VOLTAGE REGULATOR

OPERATING UNDER EXTREME ADVERSE CONDITIONS
For operation under extreme adverse conditions ( le. lightning strikes etc.) the regulator may be used
without additions, provided the power terminal (B) is connected to a centre tap of the alternator (ie. on 240
volt machine, connect terminal B to a 120 volt tap).
Where a centre tap is not available, an isolation step down transformer may be used to supply power to
terminal B – see diagran. Contact the factory for VA rating of transformer, stating alternator serial number.
Where severe transients may be induced by direct lightning strikes, lightning supperssors should be used
on alternator outputs.
